Abstract
By applying the q{derivative, M{series, convolution an subordination struc- tures, we introduce a new subclass of univalent functions. For this subclass of functions, we obtain coecient inequality, convexity and convolution preserving property. Some consequences of geometric properties are also considered.
Keywords
